Problems with conversion about numbers, may global option?!

[guidiego]

We are using this lib here, and I found a small problem. Usually, we do not split numbers from the case, for example:

myItem1 -> my_item1.

With ts-case-convert we get my_item_1, I think because of how this line works: https://github.com/RossWilliams/ts-case-convert/blob/main/src/caseConvert.ts#L70-L74

I was thinking if is possible not to add _ before the number (I think that makes more sense) or at least add a configuration to tell how I would like to convert this kind of thing
